DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In various embodiments, a lighting system is provided for use with log sets. As used herein, the term “log set” is a broad term used in its ordinary sense, and includes any of a variety of flame-producing units that include ornamental, decorative, or synthetic logs that are substantially noncombustible. Log sets generally include vented units, which are configured for operation in a vented environment (e.g., in a fireplace having an open flue), and vent-free units, which are configured to operate in an unvented environment, such as a substantially sealed room.

In some embodiments, the lighting system is configured to provide ambient or accent lighting and thus enhance the aesthetic properties of the log set. In some embodiments, the lighting system is included with the log set as part of a log set kit, and in other embodiments, the lighting system may be provided separately as an accessory to the log set. In many embodiments, the lighting system provides a convenient and/or economical alternative to accent lighting systems currently in use with certain direct vent fireplaces and fireplace inserts, referred to herein as direct vent devices, and overcomes problems and limitations associated with such accent lighting systems.

Direct vent devices generally include a firebox, cavity, or combustion chamber and an outer casing that is spaced from and substantially surrounds a portion of the combustion chamber. The combustion chamber generally sustains a controlled burn of gaseous fuel, and thus can be heated to relatively high temperatures (e.g., about 800° Fahrenheit in some units). In some embodiments, the upper portion of the direct vent device includes coaxial inlet and outlet vents through which relatively cool air may enter the region between the combustion chamber and the outer casing and through which heated air may escape from the combustion chamber, respectively. The outer casing is generally mounted in a wall of a house or other structure such that only the combustion chamber and, in some instances, a decorative facade are visible. Accent lighting systems used with direct vent devices are generally designed to enhance the aesthetic properties of one or more sidewalls of the combustion chamber. However, such accent lighting systems suffer from a variety of drawbacks.

For example, direct vent devices that include such accent lighting systems can be expensive, and further, can require complicated and/or expensive installation. For example, such devices can sell for thousands of dollars, not including installation fees. In many instances, such devices include a variety of interconnected components and detailed instructions regarding proper installation techniques. Often, the installed units must be in compliance with various building codes and legal regulations. Additionally, the units generally require dedicated electrical hardwiring (e.g., 110V AC) for fans and/or accent lights. Accordingly, the units generally must be installed by a qualified professional, and often are installed during construction or remodeling of a home or other structure.

In many instances, direct vent devices produce relatively bright flames. For example, some devices produce vibrant flames with a substantially yellow hue. As a result, units that include accent lighting systems generally include bright lights in order for the accent lighting to be perceptible. Therefore, some accent lighting systems include relatively high wattage bulbs or lamps (e.g., 75 watt halogen lamps). Such lamps can require a significant amount of current for operation, and thus generally require electrical hardwiring.

Additionally, in many instances, such lamps are heat-sensitive and thus must be strategically positioned within a direct vent device for cooling purposes. As noted above, the combustion chamber is generally spaced from the walls and/or the base of the outer casing, thus a floor or partition of the combustion chamber can be spaced above a base of the outer casing and define a lower region or bottom portion of the outer casing. In operation, relatively cool, oxygenated air circulates in the lower region of the casing and enters the combustion chamber via one or more vents in the floor of the combustion chamber. As a result, lamps for accent lighting systems are generally located below the floor or partition of the combustion chamber.

The lamps are thus generally recessed relative to the base of the inner chamber, and are cooled by the relatively cooler air in the space beneath the base. Furthermore, such lamps can be sensitive to dust, pet hair, and other common household debris capable of being carried in convective air currents. Accordingly, direct vent devices generally include transparent or translucent covers or lenses that shield the lamps from heated air and/or debris. Accent lighting systems that are suitable for the controlled and shielded environments of certain direct vent devices are unsuitable and/or infeasible for the less controlled environments in which log sets often operate, as discussed below.

In contrast to direct vent devices, log sets are generally substantially portable units that can be cheaper, can include fewer components, and can be quicker and easier to install. Rather than selling for thousands of dollars, many log sets are priced in the hundreds of dollars range. Log sets thus generally appeal to a different consumer base than do direct vent devices. Many log set consumers are attracted to the lower pricing of log sets and the reduced installation efforts they entail. As a result, it would be advantageous to provide an ambient or accent lighting system operable with log sets that does not significantly add to the cost and/or complexity of installing a log set.

However, hardwired electrical sources generally are not accessible for use with log sets. Unlike many direct vent devices (described above), log sets generally do not include an inner combustion chamber and an outer casing, and thus do not include a cooled and/or protected environment between such a combustion chamber and outer casing in which sensitive electrical components can be stored. Rather, log sets are often configured to be placed on a floor of a fireplace firebox, a recessed cavity, or any other suitable structure. Such structures generally do not include electrical hardwiring. For example, log sets are often installed within the fireboxes of wood-burning fireplaces with gas starters, which generally do not include electrical hardwiring.

Further, log set consumers are not likely to run electrical hardwiring to a log set. Log sets and components thereof are generally exposed to the heated environment that results from operation of the log set, thus electrical hardwiring could potentially be hazardous, unless additional installation procedures and precautions are taken. Such procedures and precautions would add to the time, complexity, and cost of installing a log set, which many log set consumers wish to avoid.

Additionally, log sets generally do not provide an environment that is amenable to light bulbs or lamps that are sensitive to heat and/or airborne debris. As previously noted, log sets generally do not include an inner combustion chamber and an outer casing, and thus do not include a cooled and/or protected environment between such a combustion chamber and outer casing in which sensitive lighting components can be stored. Furthermore, even if known accent lighting systems were to be installed below the floor of a cavity in which a log set may be installed, the lenses or covers of such systems would undesirably accumulate dust and other debris, which can be more likely to collect in the less controlled environment in which log sets often operate.

Described herein are embodiments of lighting systems for use with log sets that overcome some or all of the above-noted deficiencies of direct vent devices and/or solve some or all of the problems associated with providing ambient light to a log set. For example, various embodiments are relatively inexpensive, relatively easy to install, and/or are operable in the same chamber or structure as an associated log set. Other uses, advantages, and desirable features will be apparent from the detailed description of various embodiments that follows.

FIG. 1 depicts an embodiment of a log assembly 10. In various embodiments, the log assembly 10 can comprise any suitable aftermarket log assembly configured for relatively simple installation, gas log set, gas log system, gas log unit, gas log heater, gas log, gel log set, gel log unit, gel log heater, solid fuel log set, solid fuel log system, log system, log assembly, and/or firelog set. In certain embodiments, the log assembly 10 is sized to be positioned within a chamber, a recess, or a cavity 20, which can include a floor 25. In various embodiments, the cavity 20 comprises the firebox of a fireplace, a gas log firebox, or any other suitable structure for housing the log assembly 10. In some embodiments, the floor 25 is substantially planar, and in further embodiments, can be substantially horizontal. In other embodiments, the cavity 20 can comprise a base portion of a firepit. In some embodiments, the floor 25 is substantially rounded or bowl-shaped. Other configurations of the cavity 20 and/or the floor 25 are also possible. Desirably, the cavity 20 includes and/or is positioned near a wall (e.g., a back wall) or the like on which a lighting pattern may be projected.

In certain embodiments, the log assembly 10 includes one or more substantially noncombustible logs 30. The logs 30 can be formed of any suitable material, such as, for example, clay, cement, and/or ceramic fiber. In some embodiments, the log assembly 10 includes substantially noncombustible floor cover, such as embers 35. The logs 30 and embers 35 can be arranged in a variety of configurations to simulate natural logs and embers.

In certain embodiments, the log assembly 10 includes a lighting system 40 (see, e.g., FIG. 3) that can produce a lighting pattern 42 on one or more walls 44 and/or the floor 25 of the cavity 20. Desirably, the lighting system 40 creates a pleasing ambient light. As further discussed below, the lighting system 40 can illuminate at least a portion of the logs 30 and/or the embers 35 in addition to or instead of illuminating the walls 44 and/or the floor 25. In many embodiments, the log assembly 10 is configured to produce a flame 46.

With reference to FIGS. 2-4, in certain embodiments, the log assembly 10 includes a housing or frame 50. In some embodiments, the frame 50 defines a substantially polygonal perimeter. In the illustrated embodiment, the frame 50 defines a substantially trapezoidal perimeter, with a longer end of the trapezoid at a front portion of the frame 50. Other suitable configurations are also possible.

In some embodiments, the frame 50 includes a foundation, bottom surface, or base portion 52 configured to rest on the floor 25. As best illustrated in FIG. 2, in certain embodiments, the base portion 52 includes one or more lateral extensions 54 that project outward from the frame 50. In some embodiments, the lateral extensions 54 are substantially coplanar such that the base portion 52 defines a substantially planar lower spatial extent 56 (see FIG. 3) of the frame 50. In some embodiments, the lower spatial extent 56 of the frame 50 is substantially coplanar with the floor 25 when the frame 50 is resting on the floor 25. The lower spatial extent 56 of the frame 50 thus defines a plane beneath which no portion of the assembly 10 extends, as further described below.

In certain embodiments, the base portion 52 includes one or more surfaces or walls 60 that project upward from the lateral extensions 54. In some embodiments, the walls 60 are substantially planar. In some embodiments, a rear wall 60 a is taller than one or more of the remaining walls 60, such as a front wall 60 b. The rear wall 60 a can include upward projections 62 configured to couple with one or more logs 30. The projections 62 can include slots 64 through which mounting hardware, such as, for example, bolts, can be coupled with the one or more logs 30. In some embodiments, the rear wall 60 a includes one or more openings 66. The openings 66 can advantageously reduce material costs and/or allow circulation of air through the frame 50. In some embodiments, the rear wall 60 a can include apertures (not shown) through which hardware can be advanced to couple the lighting system 40 with the frame 50, as discussed further below.

In other embodiments, the base portion 52 includes legs, props, supports, struts, pegs, or other suitable base structures configured to elevate the frame 50, and/or other structures coupled therewith, from the floor 25. In some embodiments, the base portion 52 does not include walls 60.

In some embodiments, the frame 50 is configured to be substantially hidden from view when logs 30 are placed thereon. For example, in some embodiments, a substantially trapezoidal-shaped frame 50 that slopes upward from a wide portion at the front wall 60 b to a narrower portion at the rear all 60 a can provide a suitable base for supporting multiple logs 30, that can hang over the edges of the frame 50 at rearward positions.

In certain embodiments, the frame 50 is configured to support at least one of the logs 30. The frame 50 can include one or more support surfaces, ledges, or shelves 70 for supporting the logs 30, and in some embodiments, one or more of the shelves 70 are substantially planar. In some embodiments, two or more of the shelves 70 are at different distances from the lower spatial extent 56 defined by the base portion 52. In further embodiments, the one or more shelves 70 are substantially horizontal when the frame 50 rests on the floor 25.

With continued reference to FIGS. 2-4, in certain embodiments, the log assembly 10 includes a grill, rack, or grate 80. In some embodiments, the grate 80 is coupled with frame 50, and in other embodiments, the grate 80 is integrally formed with the frame 50. The grate 80 can be configured to support one or more logs 30 and/or to simulate similar structures used in natural wood-burning fireplaces.

In some embodiments, the log assembly 10 includes a burner 90. Any suitable variety of burner 90 is possible. In some embodiments, the burner 90 includes a base plate 92 (best illustrated in FIG. 2) and a cover plate 94 (best illustrated in FIGS. 3 and 4). In certain embodiments, the base plate 92 is substantially solid, but can include an opening (not shown) through which fuel can be introduced into the space between the base plate 92 and the cover plate 94. With reference to FIGS. 3 and 4, in certain embodiments, the cover plate 94 includes a plurality of vents 96 configured to project a flame upward from the burner 90. In certain embodiments, various properties of the flame produced by the burner 90 can be adjusted by the size, shape, arrangement, and/or number of vents 96 in the cover plate 94.

In some embodiments, the burner 90 includes positioning studs or posts 100 configured to orient one or more logs 30. In some embodiments, the frame 50 includes posts in addition to or instead of the posts 100. In certain embodiments, the assembly 10 includes a safety pilot 101, which can be positioned at a top edge of the burner 90. Other arrangements are also possible.

With reference to FIG. 2, in certain embodiments, the frame 50 and/or the burner 90 define a volume of space or cavity 102. In some embodiments, the cavity 102 is configured to house some or all of a fuel delivery system 103. In various embodiments, the fuel delivery system 103 includes a control valve 104, tubing 106, and/or a plenum tube 108. In some embodiments, the control valve 104 is configured to regulate the amount of fuel supplied to the burner 90. The control valve 104 can be coupled with the tubing 106, which can be configured to channel, direct, or route fuel from the control valve 104 to the plenum tube 108. In some embodiments, the plenum tube 108 is coupled at a first end with the tubing 106 and at a second end with the burner 90.

As shown in the illustrated embodiment, in certain embodiments, all, or substantially all, of the fuel delivery system 103 can be within the cavity 102 defined by the frame 50 and/or the burner 90. Other configurations are also possible. For example, in some embodiments, some or all of the fuel delivery system 103 can be outside of the cavity 102. In some embodiments, all, or substantially all, of the fuel delivery system 103 is substantially above the lower spatial extent 56 defined by the base portion 52 of the frame 50.

In certain embodiments, the cavity 102 can further house wiring 110 for coupling various elements of the assembly 10. In some embodiments, controls, such as one or more knobs 112 a, b, switches 114 a, b and/or buttons 116 are coupled with various components of the assembly 10 within the cavity 102 through one or more front edge walls 60 c, 60 d of the base portion 52, as shown in FIGS. 2 and 4. In some embodiments, the knob 112 a is configured to transition the valve 104 between an “on” and an “off” configuration, and the knob 112 b is configured to adjust the amount of fuel delivered to the burner 90 via the valve 104. The control valve 104 can be configured to receive fuel from a fuel source through a port 118 in a side wall 60 e of the base portion 52, as shown in FIGS. 2 and 3. For example, in some embodiments, the control valve 104 can be coupled through the port 118 with natural gas or propane gas piping.

In some embodiments, the switch 114 a is configured to transition an igniter of the pilot 101 between an active and inactive state, and when the igniter is in the active state, the button 116 is configured to fire the igniter when depressed. In some embodiments, the switch 114 b is configured to activate or deactivate the light assembly 40, as further described below.

With reference to FIG. 3, in certain embodiments, the lighting assembly 40 is coupled with the frame 50 in any suitable manner. In some embodiments, the lighting assembly 40 comprises a lighting frame, case, or housing 120, described in more detail below, that can define a mounting flange 122. In some embodiments, the mounting flange 122 includes one or more apertures 124 through which mounting hardware, such as screws, can be advanced to secure the housing 120 to the frame 50. As mentioned above, in some embodiments, the mounting flange 122 can be coupled with the rear wall 60 a.

In some embodiments, the lighting housing 120 is substantially hidden from view from a position in front of the frame 50 when the housing 120 is coupled with the frame 50. Accordingly, in certain embodiments, a viewer positioned in front of the frame 50 may see the lighting pattern 42 produced by the lighting assembly 40 without seeing the lighting assembly 40. In some embodiments, the lighting housing 120 is elevated above the lower spatial extent 56 defined by the base 52 when the lighting housing 120 is coupled with the frame 50.

In some embodiments, the lighting housing 120 can be cooled by circulating air. For example, in some embodiments, the burner 90 can create convective air currents such that relatively cool air and, in certain cases, airborne debris within the cool air, can be drawn into the cavity 20. In some embodiments, the cool air can enter the cavity 20 and circulate about the lighting housing 120 and other components of the assembly 10 without first passing through a vent, in contrast to the arrangements described above with respect to certain direct vent devices.

In some embodiments, the lighting housing 120 is detachably coupled with the frame 50 in any suitable manner. For example, in some embodiments, the lighting housing 120 comprises one or more magnets (not shown). In various embodiments, the magnets can be located at an interior of the housing 120 or at an exterior surface of the housing configured to face and/or abut the rear wall 60 a. In other embodiments, one or more of the lighting housing 120 and the frame 50 can comprise latching, locking, or sliding components configured to engage and disengage with relative ease. In some embodiments, the lighting assembly 40 can produce light when the housing 120 is detached from the frame 50.

With reference to FIG. 5, in certain embodiments, the lighting housing 120 is formed of any suitable material to provide structure to the lighting housing 120. In some embodiments, the material is capable of withstanding relatively high temperatures without substantially melting or deforming. For example, in some embodiments, the lighting housing 120 comprises metal. In some embodiments, the lighting housing 120 includes a front face or surface 130 and a rear surface 132. In some embodiments, the front and rear surfaces 130, 132 are substantially planar, and in further embodiments, are substantially parallel. In some embodiments, the front surface 130 comprises the mounting flange 122 described above. The front surface 130 can be configured to abut the rear wall 60 a of the frame 50.

In certain embodiments, the lighting housing 120 includes a bottom surface 134, which in some embodiments, is substantially perpendicular to one or more of the front and rear surfaces 130, 132. In some embodiments, the bottom surface 134 is configured to rest on the floor 25 of the cavity 20. Accordingly, in some embodiments, the lighting housing 120 can stand apart from and/or be spaced from the frame 50, and in further embodiments, can be selectively positioned by a user to create a desired lighting pattern. In some embodiments, the lighting housing 120, or a substantial portion thereof, can be covered and/or hidden from view by embers 35.

In some embodiments, the lighting housing 120 includes a top surface 136. In some embodiments, the top surface 136 is substantially arcuate, bowed, or rounded. The top surface 136 can define a substantially semicircular arch, or can define a curve that conforms to other rounded surfaces, such as, for example, an ellipse, a parabola, or a sphere. In some embodiments, the top surface 136 is recessed relative to the front and rear surfaces 130, 132. In certain embodiments, the top surface 136 includes one or more receptacles, mounts, or sockets 138. In some embodiments, one or more of the sockets 138 define an outer flange 139 that extends upward from the top surface 136. In some embodiments, an inner surface of the outer flange 139 is substantially reflective. In certain embodiments, the sockets 138 are configured to receive and/or house one or more light sources 140. In some embodiments, the light sources 140 are substantially within the outer flanges 139 defined by the sockets 138.

In certain embodiments, the lighting housing 120 includes one or more arrays 142 of light sources 140. In various embodiments, an array 142 includes no less than two, no less than three, no less than four, no less than five, or no less than six light sources 140. In some embodiments, an array 142 includes three or fewer light sources 140, and thus can constitute a minor array. In some embodiments, an array 142 includes four or more light sources 140, and thus can constitute a major array. In some embodiments, the light sources 140 are substantially aligned with each other within a plane, which can extend through the top surface 136. In some embodiments, such as the illustrated embodiment, the plane is vertical and substantially parallel to one or more of the front and rear surfaces 130, 132 of the lighting housing 120. The plane can also be horizontal or oriented at an angle with respect to the floor 25. In some embodiments, the light sources 140 are spaced from each other at regular intervals along the top surface 136 of the lighting housing 120. In some embodiments, two or more sets of adjacent light sources 140 are spaced from each other by equal amounts. In some embodiments, regularly spaced light sources 140 can provide a regular pattern 42 on one or more walls 44 and/or the floor 25 of the cavity 20.

Other arrangements of the light sources 140 are also possible. In some embodiments, the light sources 140 are unaligned and/or are spaced from each other by irregular or unrepeated intervals. In various embodiments, the light sources 140 are arranged in different patterns, such as, for example, a circle or an arch. In some embodiments, different light sources 140 are angled differently within the sockets 138.

In some embodiments, optical elements are optically coupled with one or more of the light sources 140. For example, in some embodiments, a light source 140 is received within a socket 138, and one or more of a reflector, diffuser, or lens is also received within or over the socket 138. The one or more optical elements can serve to direct a light beam, diffuse a light beam, and/or shield the light source 140 from direct contact with heated air.

In certain embodiments, the light sources 140 comprise one or more light-emitting diodes (LEDs). In various embodiments, the LEDs are configured to produce a substantially red, substantially orange, substantially yellow, and/or substantially white hue. In some embodiments, the LEDs include tinted plastic casings that can affect the color produced by the LEDs. Other coloring features, such as color filters, may also be used with the LEDs. In some embodiments, the LEDs are configured to operate in relatively high temperature environments, and can include so-called “high temperature” LEDs. In various embodiments, the LEDs are operational at a temperature of about 80° C. or more, about 110° C. or more, or about 120° C. or more. In other embodiments, the LEDs are operational at higher temperatures. For example, in some embodiments, the LEDs are operational at a temperature of about 200° C. or more or about 250° C. or more. Other temperatures at which the LEDs are operational are also possible.

In certain embodiments, use of LEDs for the light sources 140 can be advantageous, as compared with certain bulbs or lamps. In some embodiments, LEDs are packaged in plastic housings or casings and can be relatively more robust (e.g., less affected by dust or other airborne debris). Additionally, LEDs can operate at lower wattage than such bulbs, as further discussed below. In certain embodiments, LEDs are more directional than some lamp arrangements, which can allow greater control over which portions of an environment receive ambient lighting. For example, in some embodiments, the LEDs can be directed to form the substantially six-lobed lighting pattern 42 illustrated in FIG. 1. Other lighting patterns and arrangements are also possible.

In certain embodiments, the top surface 136 of the lighting housing 120 cooperates with the front, rear, and bottom surfaces 130, 132, 134 to form an enclosure 150. In some embodiments, the enclosure 150 houses at least a portion of electrical circuitry (described further below) for operating or controlling the lighting assembly. In some embodiments, the enclosure 150 includes insulation to protect the circuitry from a heated environment created by the log assembly 10.

With continued reference to FIG. 5, in certain embodiments, the lighting assembly 40 includes one or more lighting lanyards, wires, or cords 160. In some embodiments, the lighting cords 160 are coupled with the lighting housing 120, and in further embodiments, extend from and/or through one or more surfaces, such as side surfaces 162, of the lighting housing 120.

In certain embodiments, a lighting cord 160 includes one or more light sources 141 at a distal end thereof. In some embodiments, the one or more light sources 141 are movable relative to the frame 50, and can be selectively positioned by a user. In various embodiments, one or more light sources 141 can be positioned to illuminate one or more of the logs 30, at least a portion of the embers 35, and/or a portion of the cavity 20, such as the floor 25 and/or the walls 44. Accordingly, in some advantageous embodiments, a user can create one or more lighting patterns 42 suited to his or her own taste. In some embodiments, the lighting cord 160 can be substantially hidden from view by the embers 35 and/or the logs 30.

In certain embodiments, the lighting cord 160 comprises a material configured to maintain the lighting cord 160 in a shape once the cord is positioned in that shape. For example, in some embodiments, the lighting cord 160 includes an insulated metal that can be bent or deformed to a desired shape.

In various embodiments, one or more of the light sources 140, 141 can be mounted such that they are relatively fixed with respect to the cavity 20 and/or the frame 50. In some embodiments, the light sources 140, 141 are included in the lighting housing 120. The light sources 140, 141 can be mounted to the frame 50, the floor 25, the walls 44, and/or any other suitable structure. In various embodiments, one or more of the light sources 140, 141 can be independently moveable or positionable relative to the frame 50. In some embodiments, the light sources 140, 141 can be manually movable or manually positionable. As used herein, the term “manually positionable” means capable of being moved without the use of tools. In various embodiments, one or more arrays 142 of light sources 140 are mounted and or moveable.

In certain embodiments, the lighting assembly 40 includes a dedicated, portable, confined, exclusive, local, or localized power source 170. As used herein, the term “localized power source” is a broad term used in its ordinary sense, and includes any of a variety of power sources that function separately and independent of electrical hardwiring of a building or location (such as a patio) in which the localized power source is located. In certain embodiments, the power source 170 is electrically coupled with and is configured to provide electrical energy to the one or more light sources 140, 141.

In some embodiments, the power source 170 includes one or more batteries 172. For example, in some embodiments, the batteries 172 comprise two size “D” batteries. Any other suitable number and/or size of batteries is possible. Any other suitable localized power source may also be used.

In some embodiments, the power source 170 includes an outer casing 174. In some embodiments, the casing 174 comprises a material configured to substantially maintain a shape without melting or deforming in a heated environment, such as metal. In some embodiments, the casing 174 includes insulation. In some embodiments, the casing 174 includes at least a portion of electrical circuitry for controlling or operating the lighting assembly 40.

In various embodiments, the power source 170 is positioned within, substantially within, without, or substantially without the cavity 102 defined by the frame 50 and/or the burner 90. For example, in the embodiment illustrated in FIG. 2, the power source 170 includes a casing 174 that is positioned within the cavity 102. In other embodiments, the casing 174 is spaced away from the cavity 102. In some embodiments, the power source 170 can be substantially hidden from view by one or more of the frame 50, the burner 90, the logs 30, and/or the embers 35.

In certain embodiments, the power source 170 is coupled with an actuator 180. In some embodiments, the actuator 180 is configured to transition the lighting assembly 40 between an “on” operational state and an “off” operational state. For example, in certain embodiments, the actuator 180 comprises the switch 114 b (also illustrated in FIG. 4), which can be configured to rotate between an “on” position and an “off” position. In certain embodiments, one or more of the light sources 140, 141 is selectively illuminated when the actuator 180 is in an activated state.

In certain advantageous embodiments, the power source 170 provides power to the lighting assembly 140 without hardwiring or other connection with the electrical wiring of a building or other structure in which the log assembly 10 is installed. Accordingly, in some embodiments, the log assembly 10 can be a substantially self-contained unit for which little or no alterations are made to an existing cavity 20 for installation of the log assembly 10. In further embodiments, the power source 170 and/or the other portions of the lighting assembly 40 comprise relatively inexpensive components, and thus can add to the cost of a log assembly 10 by only a small fraction thereof. Therefore, in certain embodiments, the lighting assembly 40 can be a particularly useful addition to relatively inexpensive, aftermarket log sets because the lighting assembly 40 may add little expense and/or few or no additional installation steps.

In certain embodiments, use of LEDs for one or more of the light sources 140, 141 can be advantageous because LEDs can operate at lower wattages than certain light bulbs and lamps. Accordingly, in some embodiments, LED light sources 140, 141 are suitable for use with a power source 170 comprising one or more batteries 172. In some embodiments, LEDs are dimmer than certain higher wattage light bulbs and lamps. Accordingly, in some embodiments, LEDs are well suited for use with certain embodiments of the log assembly 10. For example, some log sets can produce dimmer flames than certain direct vent devices. Furthermore, in many instances, log sets are capable of delivering more heat to rooms in which they are installed than are certain direct vent devices. Accordingly, users often operate log sets on a relatively low setting, which can also produce a dimmer flame. Therefore, in certain embodiments, LEDs can advantageously provide relatively bright lighting patterns when used with log sets, even when operating at lower wattages than some direct vent device ambient lighting systems. Although LEDs can advantageously be used in some embodiments, any other suitable light source, which may or may not include any or all of the advantages noted herein, can be used.

In some embodiments, the lighting assembly 40 includes a remote control 190. The remote control 190 can include one or more actuators, switches, or buttons 192 by which an operational state of the lighting assembly 40 can be selected. Advantageously, the remote control 190 can permit a user to select an operational state of the lighting assembly 40 at a distance from the burner 90 when the burner 90 produces a flame. In certain embodiments, the one or more buttons 192 can be activated to selectively illuminate and/or selectively deactivate one or more of the light sources 140. In certain embodiments, the actuator 180 is placed in the “on” configuration in order for the lighting assembly 40 to respond to signals sent by the remote control 190. In certain embodiments, the remote control 190 comprises the actuator 180. For example, in some embodiments, a button on the remote control 190 is actuated to power on the lighting assembly 40.

In certain embodiments, the lighting assembly 40 includes a variety of lighting and timing features. For example, in some embodiments, a user can select the amount of time the light sources 140, 141 are to remain illuminated. In some embodiments, a user can select one or more of the lighting and timing features via the remote control 190.

In certain embodiments, the lighting assembly 40 can be separate from a log assembly 10. In some embodiments, the lighting assembly 40 is configured to couple with any of a variety of log sets. Accordingly, in some embodiments, previously installed log sets can be retrofit to include the lighting assembly 40. For example, in some embodiments, the lighting assembly 40 includes one or more light sources 140 within a lighting housing 120 that can be selectively positioned within a cavity 20. In some embodiments, the lighting assembly 40 includes mounting hardware configured to couple the lighting housing 120 with a frame of a log assembly 10.

With reference to FIG. 6, in certain embodiments, the remote control 190 is configured to couple with a second remote control (not shown). Accordingly, in some embodiments, the remote control 190 is very small in comparison with many standard remote controls, such as remote controls that are configured to ignite the burner of a log set and/or adjust the flame size of the log set. In some embodiments, the remote control 190 includes a linkage, connection, or adhesion portion 194 configured to permanently or temporarily attach the remote control 190 with the second remote control. In certain embodiments, the adhesion portion 194 is located opposite the one or more buttons 192. In some embodiments, the adhesion portion 194 includes a glue or epoxy. In some embodiments, the adhesion portion 194 includes one or more complementary portions of hook and pile fastener. Other suitable attachment methods and/or devices are also possible.

Accordingly, in some embodiments, the remote control 190 is particularly well-suited for inclusion with a separately sold, retrofit lighting assembly 40. For example, some log sets include remote controls for starting a flame and/or adjusting the height of the flame. In some instances, it can be burdensome for a user to have two separate remote controls for operation with a single log set. Accordingly, certain embodiments of the remote control 190 that include an adhesion portion 194 can advantageously permanently or temporarily join two separate remote controls into a single unit. In other embodiments, the lighting assembly 40 can include a universal remote control configured to operate the lighting assembly 40 and numerous different log set models.

FIG. 7 depicts a schematic diagram of an embodiment of a receiver circuit 200 compatible with certain embodiments of the log assembly 10. In some embodiments, the receiver circuit 200 receives a signal from a remote control unit, such as the remote control 190, and transmits the signal to a lighting system, such as the lighting assembly 40, causing one or more lights, such as one or more light sources 140, 141, to turn on. In one implementation, the receiver circuit 200 includes a power supply circuit 210 that supplies power from a battery 212 or other power source to various circuit components. Optionally, the power supply circuit 210 also supplies power directly to the lighting system.

An antenna 220 can receive a signal from a remote control unit operated by a user. In one embodiment, the signal is a radio frequency signal, such as an ultra-high frequency (UHF) signal. The antenna 220 transmits the signal to a receiver integrated circuit 222, which in some embodiments, comprises a UHF receiver. The receiver integrated circuit 222 can recover a digital signal 224 encoded in the radio frequency signal. The receiver integrated circuit 222 can then pass the digital signal 224 to a processor 230.

In one implementation, the processor 230 comprises a microcontroller, such as an 8-bit PIC microcontroller or the like. The processor 230 can include a program code for manipulating the digital signal 224. The program code in one embodiment enables the processor 230 to transmit a second digital signal 232 to a relay 240, transistor, or other digitally-controlled switch. The relay 240 then activates a switching network 250 that provides an output signal to an output port 252 connected to one or more lights in the lighting system. In another embodiment, the processor 230 sends an output signal to a transistor 260, which activates one or more lights through a second output port 262. Additional output ports may be included to accommodate additional lights.

The program code may be configured to turn on or turn off the lights. Alternatively, the program code may be configured to cause the lights to flash, blink, or turn on and off at regular or irregular intervals. In certain embodiments, the user can therefore control a pattern of the lights in the lighting system.
